Abstract: A microstrip antenna (4) has a radiation electrode (2) and a ground electrode (3) which are formed on upper and lower surfaces of a dielectric substrate (1) respectively. A feeding terminal electrode (2c) of the radiation electrode (2) is formed on the lower surface of the dielectric substrate (1), which is provided with the ground electrode (3), and is insulated from the ground electrode (3). A feeding point (2a) of the radiation electrode (2) is connected with the feeding terminal electrode (2c) by a through-hole electrode (2b). The feeding terminal electrode (2c) is formed in the same plane as the ground electrode (3). In another embodiment of the invention, a through-hole electrode (12b) extends from a feeding point (12a) to the plane of the ground electrode (13).

Abstract: A connector is disclosed which is to be mounted to a coaxial cable having an internal conductor, an internal insulator, cable outer (or shield) conductor, and a cable outer insulator. The connector comprises a housing formed of a connector outer conductor and a concentric inner contact. The connector outer conductor includes a cylindrical main portion and a rear cover portion. An outer conductor adapter is fixed to the main portion of the connector outer conductor and is adapted for insertion between the internal insulator and the cable outer conductor of the coaxial cable. A sleeve portion, which can include either a single securing member or two securing members to be wrapped about the coaxial cable, is formed integrally with the connector outer conductor. The inner contact is provided at its rear end with a slot into which the internal conductor is to be thrust, and at its forward end with a plurality of slits to provide an elastic firm holding force for holding a mating contact of another cable.
